Synopsis

This story explains how to build a fascinating wood model in which one revolution of the hand crank indexes a gear one tooth. This model illustrates the basic mechanical principle of ratcheting devices. Everyone who operates the finished model will be mesmerized watching how it works.

This story includes the patterns for making a pretty neat mechanical model. If you are a woodworker, your normal practice may be to use paper patterns to attach to the wood blanks to cut out the component pieces.

I ran an experiment where I tried to photocopy the display from a Kindle. It photocopied onto paper fine. You should be able to photocopy my patterns in the Kindle story onto paper so you attach (e.g. glue) the pattern to the wood blank.

If you are reading this story using the Kindle for PC software, you can print the patterns by taking screen shots (hit print screen key) and pasting them into another program like the free IrfanView software. You can print the patterns from IrfanView.
